Ventilator



Patented Mar. 31, 1931 UNiTED STATES ERNEST O. DANIELS, F ORANGEVILLE,ONTARIO, CANADA vENrIL i'roR Application filed July 31, 1929, SeriaI NO,

This invention relates to devices adapted to be either permanently ordetachably secured to theupper part of a window, provided with avertically sliding pane, to provide an air exit and my object is todevise a simple and inconspicuous ventilator of this type con- 7trollable by the raising or lowering of the sliding pane.

I attain my object by providing a hood 10 adapted to be fitted at thetop of the window frame and having a bottom extending in-' wardlytowards the outer surface of the sliding pane. In this bottom are formedventilating openings of louverlike form. To

the inner side of the hood is secured a flexible strip contacting withthe sliding pane.

Preferably the tongues are of such a width that the walls of thehood-form the inner and outer sides of the louvers. In the inner wallare formed suitable openings through which air passes to the interior ofthe vehicle.

The device is constructed in detail substantially as hereinafter morespecifically described and as illustrated in the accompanying drawingsin which Fig. 1 is a vertical section showing my device applied to awindow; and

Fig. 2 a perspective view of vice on a larger scale.

In the drawings like numerals of reference indicate corresponding partsin the different figures.

In the drawings 1 is a frame in which is slidably mounted theglass pane2. Secured to or forming part of the top of the frame is the ventilatorhood, which is integrally formed of sheet metal bent to U-forin, '3being the outer wall, 4: the inner wall, and 5 the bottom, which extendscomparatlvely part of the declose to the pane 2.

In this bottom are formed a series of openings 5 through which air maypass. As it isdesirable that the passage of air should be from withinoutward, these openings are formed as louvers so that the movement ofthe vehicle, to which the device is applied. causes air to be drawnoutwardly through the openings. These louvers are preferably formed by,stamping up tongues 6 from the metal of the flange, which tongues are soposi- 382,386, and in GanadaMarch 25, 1929.

' the inner wall 4 is a flexible strip 10 of rubber or other suitablematerial which is adapted to'engage the outer surface of the glass pane2, thus preventing the inward passage of air between the ventilatingdevice and the glass pane. This strip may be of any suitable form andsecured in any suitable manner. I show it as of L form, one leg of whichcontacts with the glass pane while the other is cllpped to the Wall 4 bymeans of tongues 7 stamped up from the metal of the wall.

The control of the ventilation is through the medium of the glass'pane,which will be more or less raised in the usual manner to give a wider ornarrower opening above the pane beneath the hood.

From theabove description it will be seen that this construction of thedevice is very simple, as it can be entirely constructed of stampedsheet metal and readily applied to or built in the window frame. i

What I claim as my invention is:

1.. A ventilator for a window provided with'a sliding pane comprising ahood adapted to be fitted at the top of the window frame and formed ofsheet metal bent to U-forni and having a bottom extending inwardlytowards the outer surface of the sliding pane. thebottoni and inner.wall of the hood having ventilating openings formed therein.

2. A ventilator for a window provided with a sliding pane comprising ahood adapted to be fitted at the top of the window frame provided withan open side adjacent the window and having a bottom extending inwardlytowards the outer surface of the sliding pane, the bottom having louversformed therein at right angles to the pane.

3. A ventilator for a window provided with a sliding pane comprising ahood adapted to be fitted at the top of the window frame provided withan open side adjacent the win dow and having a bottom extending inwardlytowards the outer surface of the sliding pane, the bottom having louversformed therein at right angles to the pane and a flexible weather stripsecured thereto adjacent the pane.

4. A ventilator according to claim 2 in which the louvers are formed bystamped up tongues integral with the bottom and located close to theouter wall of the hood which thus forms one side of each louver and theother side of each louver is formed by upstanding portions integral withthe bottom.

5. A ventilator according to claim 2 in which the louvers are formed bystamped up tongues integral with the bottom and located close to theouter wall of the hood which thus forms one side of each louver; theother side of each louver is formed by upstanding portions integral withthe bottom and a flexible window pane engaging strip is provided clippedto the inner side of the ventilator.

6. A ventilator according to claim 2 in which the louvers are formed bystamping tongues out of the bottom close to the outer wall of the hoodwhich thus forms one side of each louver; and means are provided closingthe inner side of said lonvers.

7. A ventilator according to claim 2 in which the louvers'are formed bystamping tongues out of the bot-tom close to the outer wall of the hoodwhich thus forms one side of each louver; means are provided closing theinner side of said louvers; and a flexible window pane engaging strip isprovided clipped to the inner side of the ventilator.

8. A ventilator hood formed of sheet metal bent to U-forin, the outerwall being in'iperforate, louvers being formed in the bottom by integraltongues cut from the bottom and bent up, and openings formed in theinner wall above the louvers.

9. A ventilator hood formedof sheet metal bent to U-form, the outer wallbeing imperiorate, louvers being formed in the bot-tom by integraltongues cut from the bottom and bent up, openings formed in the innerwall above the louvers, and a flexible strip secured to said inner wall.
